To all 'whom it may oonoern:

Be it lznown thet l, Fuurvors d. Conn, et Seheneotedv, in the eountvr ot Schoneetardpr und State ot New Forli, have invented o. eertoin new end useful lmprovement in Loeomotive 'lroiling Truolis, ot' which iroprovement the following is e. specification.

llhe object ot my invention is to provide u tour wheeled trailing truck, which muy lie loooted loelow' the dre-hon ol n loeomotive, in proper relation thereto, to support the over-hanging weight in rear ot the driving wheels, without involving any chungo in the general design ot the dre-hex, ash-pain, or uueessolies, as heretofore eonstrueted, in stondurd practice, or any substantiel deteil modieotion ol the ush pon.

The improvement eloimed is hereinafter :l'tullpr set Forth.

ln the preetiee ol mp invention, relierring deseriptivelv to the speeilie emloodnnent thereol which is herein eremplihed, nud Erst to the form shown in Figs. l to d inclusive, llprovide e. truol treme eomprising two por e el side members, l, l, e. trnnsverse rear niemler, la, nud o. transverse trout inemloer, Il", the lutter loeing forwardly inclined trom the side memhers to the longitudinal oentrel lune ol the truelr und hrt-vine o tor.- wer y projeeting; rodius hor, lz, st its middle soeteted to receive o. eenter pin. "lhe members et the truelr home ere rigidly secured together, end the radius hor le, is coupled hy o. center pin, @tto e. eross tie, 3",

secured to the side memhers, 3, ot the moin treme ot the locomotive, ond to the supplemental treme members, 3, which entend 'rearwardly therefrom, uloove the trut-,lr

humo.

' A"The truolr is supported on two prt-irs oit truek wheels, t, which poire ot wheels ere xed on two truolr ailles, la, journeled in orleboxes, t, litted, in the usuel manner, in pedestals, l, drool to the side memhers or" the truck traine. Fp reterenoe to Fig. 2, it will 'he seen that, except as to the two truolr arles, the spree inside the truelr treme is entirely, open end unolostruoted hv transverse members, and, therefore, that any suitahle and preferred torni ol ssh pun mov he located shove it. 'lhe weight carried bv the truck treme acts upon the axle hores through truck equalizers, which heur, at their ends, on the axle hores, and `:ire coupled to the ends of springs, 6, on which the side niemliers or the truck treme beer.

The rear driving wheels, i', ol? the loo0motive, are fired on an mile, l, which is tted in boxes in the mein treme, 3, in the ordif nviry manner, the supported weight being transmitted to the driving leones through v springs, 8. '.lhe truck, as o. whole, is equalizecl with the rear driving wheels hy mein equelizers., 9, which ore located in forwardly and inwardly inclined positions shove the truelc treme, and are journeled by pins, 9b, in the outer ends ol upwardly and outwerdly inclined post supports, 9a, fixed on the supplemental engine trames, 3a. 'l`he forward ends of the equelizers are coupled to the lower ends of links, 8b, the upper ends of which are, in turn, coupled to the reer spring lian ers, 8, ot the -drivinuU1 wheel springs, 8. t('llhe rear end of each of t e mein equalizers, 9, bears on a. resistance device lll@ llu

,for controlling the swinging movements of move vertically in a guide, 108,

the truck, which may be of any suitable and preferred known type, and, in the instance shown, comprises a cylindrical transmission block, 10, in'which the rear end of the equalizer is itted, and which is itself fitted to secured to, and supported by, an upwardly and outwardly projecting bracket, 10b, on the supplemental engine frame, 33. The lower end ofthe block, 10, carries a shoe, 10, the lower face of which is downwardly inclined, in opposite directions, and bears on a roller, 10, journaled, in a horizontal plane, on the adjacent side member, l, of the truck frame. Swinging movement of the truck, in either directionis resisted by the frictional resistance between the roller and shoe, and the inclined surfaces of the latter act to return the truck to normal central position, when :passing from a curve to a tangent of the track.

The iirebox, 11a, of the boiler, 11, is supported, on the supplemental engine frame members, S, in any suitable and preferred manner, as byV front and rear expansion plates, 12, and the space below it being, as

before stated, unobstructed by any transverse members of the truck, other than its axles, an ash pan, 13, having any desired number and arrangement of hoppers, may be applied.

The structural modification shown in Figs. 5 to 8 inclusive, substantially accords, in general principle, and as to the form of the truck frame and its relation to the main frame' and iirebox, with the construction above described, and differs', in structural detail, therefrom,.as to the connection of the main equalizers, 9, with the truck frame, and

abutment, 9, fixed rear driving axle, as now to bedescribed. In this instance, each ofthe said equalizers is journaled on the cylindrical transmission block, 10, of the resistance mechanism, which mechanism is similar to that first described, instead of on a'post support independent thereof as in the first described construction. The rear end of the equalizer, 9, bears on an to the. adjacent supplemental engine frame, 3a, and its forward end is coupled tothe upper end of a link, 9d, the lower end of. which is, in turn, coupled to one end ofa supplemental equalizer, 9, journaled in a bearmg, 9f, on the main engine frame, and-.having its opposite end coupled to a link, 8, which is connected to the reall spring hangers, 8*?, of the driving wheel spring, 8. The application of the supplemental equalizer, 9e, enables the length of the main equalizer to be kept Within desirable limits, and facilitates its connection with the driving spring.

Figs. 9 to 13 inclusive, illustrate a further structural modification, the characteristic feature of which is a truck frame which is of integral construction, and itself performs members, 3, in a plane nearly in line with that of the forward truck axle. As shown in Fig. 11, laterally projecting arms, 14, are formed on, or dxed to, the supplemental frame members, 3, said arms having spherical faced plates, 14, near their outer ends, fitting corresponding recesses in shoes, 14h", which rest on the tops of the side members of the truck frame. By this construction,

the engine frame, in both a vertical and a horizontal plane is provided for. The forward end of the truck frame is coupled, in its central longitudinal plane, tov the main frame, by a center pin, 2, passing through a radius bar, 1, as in the instances'before described, and the truck frame is coupled, in the manner of an equalizer, to the rear spring hangers, 8a, of the rear driving wheels, by rods, 8", passing through sockets in .lateral arms, 1d, projecting forwardly from the truck frame, on opposite sides of the radius bar.

Lateral movement of the truck frame is controlled and its return to normal central position effected, when passing from a curve to a tangent ofthe truck, by a spring centering mechanism which is indicated at the left hand side of Fig. 12, and which is substantially similar to that disclosed in Letters Patent of the United States No. 773,713, granted and issued to American Locomotive Company, as my assignee, under date of November 1, 1904. inasmuch as said mechanism does not, in and of itself, form part of my present invention, and as any other suitable and preferred form of centering mechanism, may be a plied to perform its function, it need not lie herein in detail described. Figs. 14 to 17 inclusive, illustrate another structural modification in which, as in the construction shown in Figs.` l to 8 inclusive, the over-hanging weight of the locomotive which is supported by the truck, is applied to the frame thereof in a plane midway between those of the truck axles, but in which another means of equalizing the truck wheels and rear driving wheels is provided. In this instance, a friction resistance device frame, and the truck is equal- -movement of the truck frame relatively to lll lli
